FELT ROOFlNG.

SPECIFICATION forming part: of Letters Patent No. 296,163, dated April 1, 1884.

I Application filed January 7, 1884. (No model.)

To call wit-m it may concern:

Be it known that we, LEVI Hans and DENNIS Hownnrn, citizens of the United States of America, residing at Chester, in the county of fication, reference being had therein to the accompanying drawing.

Our invention relates to an improvement. in felt roofing; and it consists both in the process of preparing the roofing material, and in the method of securing to the sheathing sheets or strips of the material thus prepared, to form a water-proof roof, substantially as hereinafter more fully shown and described.

In the drawing, thefigure is a plan View, showing the method of securing the roofingsheets.

In carrying out our invention, we employ strips of tarred paper, A, each of which we perforate, as shown, near one of its longitudinal edges, and gradually fasten them upon the sheathing-boards of the roof, and as they are fastened to thesheathing suitable roofing-cemcut is applied to them, which passes through said perforations and becomes cemented to the sheathing-boards, thus holding each strip or sheet rigidly in position, The first strip is laid fiat upon the sheathing near the edge of the roof, and the second sheet is lapped over the first sheet and the perforations thereof, and the third in like manner as the second, and so continuously serictttm. The felting is thus laid in order to avoid the use of nails and strips for fastening it down, and the leakage which arises 1. A roofing consisting of the tarred-paper strips A, having perforated longitudinal edges cemented to the sheathing, the first sheet being laid flat upon the sheathing, and the second lapped over the perforations thereof, the third being in like manner lapped over the perforations of the second, and so continuously seriatim, and a surface or finishing coat, substantially as shown, and for the purpose described.

2. In a roofing, the tarred and perforated I strips A, cemented to the sheathing and coated with a mixture of broken pebbles and gravel, for the purpose described.

In testimony whereof we affix our signatures in presence of two witnesses.
